Welcome aboard, Nick.
To cliff note what a lot of people are saying, it really is a lot cheaper to just buy a Turbo car from the get-go...
But if this N/A Car is as clean as you claim, then perhaps you may want to go this route.
Because the truth hurts...Finding A70 Supras are tough to find sometimes, let alone being in GOOD condition.
If you're doing the work yourself... $2,000 would be a close ballpark figure, but this would be the bare necessities to doing the swap.

Even my lonely little Indiana Supra owning-self is on there. Then again, I'm only a hair over an hour away from Cincinatti.
